However, as discussed in Section 3.3.1, because of the higher-order Balmer lines and Balmer continuum in the \(B\)  filter, the unreddened slope in an \(F_B\)  vs. \(F_V\)  plot will not be 1.07 as predicted by Eq. 3. The [1]} and [2]} reddening estimates are thus lower limits. Using an unreddened gradient of 1.18 instead gives \(E(B-V) \approx 0.26 \pm 0.06\) .
